invention relates to rotary. steam engines and refers moreparticularly to super" turbine which will economically utilize steam from a high to an extremely. low working ripressure. j p

One obj ectof my invention is to provide a reversible super turbine'fthatlis build and economical to run. v

Another objectof my inventions to proit) vide a reversible super turbinewherein the steam pressure is'utiliz ed by applying the same'in jets tangentially to the periphery of a driving wheel provided with suitably arranged pockets. I 1 A further obj ect ofm'y'invention is to provide a reversible super turbine having a multiple of, rotors of different sizes adapted toutilize high, intermediate and low pressure 7 steam, each rotor provided with peripherally arranged partitions wherein'steam is injected.

tangentially from Y shaped'j ets, each: yet pro.- vided with cut-oil"? and reversing means.

A still furtherobj ect of my inventionis to 7 provide areversible super turbine, ofthe tri ple'expansion impacttypawith a means for instantly reversing the application of the steampressure;

valves, wherein the cut-off valves are controlledby multiple of cams and: the revers;

ing valves controlled by a 'singlelever. "I attain these objects preferably by the means illustrated in the accompanyingdraw V ings, wherein similarnumerals refer to like parts throughout the several views, in whichz i v M v Figure 1 is a :partial longitudinal section of the engine. r

Figure 7 is'a section taken on line77 of Figure 6. I

The engine is comprised of base 1, providedwith two bearings 2 and 3, split at 4: and 5,

and held togetherby bolts like 6 and 7, and

oiled by oil cups8 and 9. I e 7 These bearings carry'a shaft 10, carrying a fly wheel 11, on one end by means of the key 12, and the shaft also carries three internal cams 13,14 and 15, by means of the key 16, and a high pressure rotorwheel 17, keyed by. the key18, to the shaft 10, an intermediate pressure rotor wheel 19 keyed to the shaft 10 5 by the'key 20, and a lowpressure rotor wheel 21, keyed to the shaft 10 by means of the key 22-, w p F The wheel 17 is enclosed a framework 23, formed to provide two rings 24 and 2 5, adaptedjto slidabl'y support a multiple of cam arms,

hereinaftfi referfed to. I This casing is-provided with a steam chamber 26, that is supplied high pressure steam by means of the pipe 27 ,and steam'is fed to a multiple of Y shaped jet nozzles like 28, each e p v I, 5 nozzle being provided. with a combined cut-:

One of the most important features of my invention consists in utilizing a multiple of; double sleeve combined cut-off and reversing and in slots 33 in the periphery of the wheel,

and these partitions are held by means of bolts like 34 andipins like 35..( I

"The ring side 31 of the wheel 17 is provided with steam exhaust p rts 36, and the wheel is preferably spoked at 37.

Steam leaves the wheel 17, through the ex haust ports 36, passes into the exhaust cham- 95 Figure 4 1s a section taken onl nes 44 ber 38, and fromthence it is diverted through the passage 39, into the steam chamber 40 in the casing 4:1, which encloses the wheel 19, andfthis casing is provided with a multiple of Y jets (preferably fifteen), like 42, each having a combined cut-off and reversing valve like 29.

The steam leaves the Wheel 19, through the exhaust port 3611, passes into the exhaust chamber 43, and is directed by the passage 44 into the steam chamber 45, in the enclosing casing 46, for the wheel 21, which is provided with a multiple of Y jets, (preferably fifteen), like 47, and from this wheel the steam passes through the exhaust ports 365, into the exhaust chamber 48, which is provided with an outlet pipe 49.

These enclosing parts 23, 41, and 46, are adapted to be bolted together with bolts like 50, and supported and held upon a support 51, on the base 1, by means of bolts like 52.

The combined cut-off and reversing valve 29 is shown in detail by Figures 6 and 7, is comprised of a base 53, recessed at 54, to provide means for holding the cut off sleeve 55, with a flange 56, which sleeve is oscillatable within the outer reversing sleeve 57, and this sleeve holds the arm 58 by means of the nut 59, and washer 60.

The reversing sleeve 57 is flanged at 61, on one end and the lever 62 is attached in any suitable way to the other end, and these sleeves are sealed together by means of the Washers 62a and 62b, and 620.

The base 53 is provided with radial passages 63 and 64, which terminate against the periphery of the reversing sleeve 57, which is provided with an opening 65, adapted to register with either of these passages 63 and 64, depending upon which passage it is desirable to direct the steam into, so it is obvious that steam may be directed tangentially in opposite directions by simply moving this reversing sleeve, so that the opening 65 will register with either of these passages 63 or 64.

The cut-01'1" sleeve 55 is provided with an opening66, shown in the closed position in Figure 7, and it is obvious when this cut-off sleeve is moved far enough for the opening 66 to re ister with the opening 65, that steam will pass into the passage 63. (See Figure 7).

All of the levers 62, on the high pressure unit, are connected together by links like 67, and these links connected by the link 68 to the crank arm 69, on the shaft 70, that is providedwith a handle 71, the arm on the in termediate pressure unit connected to the crank 72, and the arm on the low pressure unit connected to the crank 73, so that when 115 the shaft 70 is reversed by the handle 71, it

is possible to instantly reverse the steam throughout the whole engine. 1

The fifteen cut-off valves are operated by.

cams, five valves on each cam like 13, as shown in Figure 4, each like valve for the high, in-

end and a link 7 6 on the other end, which link is connected to a crank like 77, that is fixed in a shaft like 78, in bearings like 79 and 80, 81 and 82, and this shaft carrying crank arms 83, 84 and 85, for the high, intermediate, and low pressure units.

It is obvious that these cams 13, 14, and 15 will oscillate a group of cut-off valves through the mechanism referred to so that the steam pressure will be applied to all these Wheels 17, 19 and 21, in the same manner.

In operation, when the wheels are running clockwise, the reversing valve 57, see Figures 7 and 8, is opened to the passage 63, and when the opening 66, registers with the opening 65, the steam can enter the jet passage 63 and the jet thrown upon the partition 32 and the cut off valve is so adjusted that the passages are only opened momentarily, when the partition is so positioned that the jet will hit it centrally and the impact of the steam jet imparted thereto.

Having thus illustrated and described the preferred embodiment of my invention, I do not wish to limit myself to the exact construction or arrangement of parts shown, since it is evident that modifications may be made therein, without departing from the spirit of the invention or scope of the claims.
